Wow, this is really good! The graphics are great, the music is nice, and the gameplay is fun. It feels very polished. There's some really cool details like all the different game over screens. It's too hard for me though. The furthest I could make it was the mini-boss of level 2.

Anyway, the grammar is a bit strange (I'm guess you're not a native speaker?) but nothing too distracting. I found the controls a little weird. For some reason, I kept getting move and aim mixed up. Maybe it would be less awkward if all the shooting controls were all on one hand? For example, arrows to move and wasd + space to aim and shoot?
